Ecology

Intro to Ecology

TermDefinition
ecology is the study of interactions of living organisms with one another and with their physical environment
population a group of individuals all the same species living in the same area
community a group of populations living in the same area
ecosystem describes the interrelationship between the organisms in a community and their physical environment
habitat place where a particular population of a species lives
niche describes all the biotic (living) and abiotic (nonliving) resources in the environment used by an organism
population size the total number of individuals in the population
population density the total number of individuals per area or volume occupied
dispersion how individuals in a population are distributed. They can be clumped (like humans in cities), uniform (like trees in an orchard), or random (like trees in some forests)
carrying capacity the maximum number of individuals of a population that can be sustained by a particular habitat
biodiversity is the variety of all living things; the different plants, animals and micro organisms, the genetic information they contain and the ecosystems they form
abiotic is the nonliving physical and chemical attribute of a system (ex: water, amount of light, temperature, wind patterns, pH, oxygen , etc.)
biotic are all of the living things in an ecosystem, such as plants and animals
limiting factors are those elements that prevent a population from attaining its maximum growth rate under ideal conditions, with unlimited resources and without any growth restrictions
biotic potential is the maximum growth rate of a population under ideal conditions, with unlimited resources and without any growth restrictions
